function [sts, vind] = checksubs_job(item, subs, dflag)

% function [sts vind] = checksubs_job(item, subs, dflag)
% Check whether a subscript reference is a valid reference in a job
% structure starting at item. subs(1) should have a subscript type of
% '.', and the subscript reference should be a tagname from item.val or
% item.values, depending on dflag.
%
% This function is identical for cfg_branch and cfg_(m)choice classes.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
